INCANbESCENT-MANTLE-LIGHTING APPARATUS.

, SPECIFICATION forming part of Letters Patent N0. 747,805, dated December 22, 1903- Applieation filed May 12, 1903.

To all whom it may concern/.-

Be it known that I, JAMES TOLSON, a citizen of Victoria, residingat Esplanade, Sandgate, in the State of Queensland, Australia,- have in- .vented a new and useful Improvement in Inburned particles of the illuminant with the oxygen of the air does not take place at all or takes place at such a distance from the surface of the mantle as to be practically useless for the purpose of incandescence.

The object of my invention is, first, to render the combustion of the illuminant as com plete as possible at or near the surface of the mantle, thereby increasing the brillianoy of the incandescence, and, secondly, to impart a portion of the waste energy contained in the consumed gases or products to theincorning air and illuminant, thereby reducing the quantity of the illuminant used as compared with that at present required. To accomplish this end, I cause the entering air and gas or vapor, or both of them, to circulate through pipes or over surfaces so arranged as to absorb the waste heat from the products of combustion issuing from the chimney.

My invention consists of a novel arrange ment whereby the heat liberated or generated by the combustion of the illuminant is utilized as far as: possible in imparting increased thermal energy to the air and illuminant about to be consumed, thereby rendering them more fully available for the production of light at a reduced cost. I

I am aware that many regenerative lamps have been designed to apply hot air and fuel for flame-lamps,'and my invention applies similar means to the incandescent -mantle lamps.

My invention also consists of a novel perforated chimney capable of admitting our rents of air to its interior. I the incomb'usti'ble constituents of the air that issue through the mantle and the partially- By this means- Serial No; 156,823. (No model.)

consumed gasesor vapors and the products of combustion that are formed within the mantle and that also issue through the mantle, all of which tend to form a more or less obstructing layer to further combustion, are broken up and mixed with the unburned air. This breaking up or mixing of any unburned or partially-burned particles of gas or vapor and air allows of their combining more rapidly and readily at or near the'surface of the mantle with the oxygen supplied from below or with that supplied through the perforations in'the chimney, or both, thereby increasing the incandescence of the mantle.

My invention further consists of a novel arrangement consisting of an illuminant-supply pipe inclosed in an air-supply pipe,whereby the illuminant and all the lower parts of the apparatus are heated by the air to which heat has been imparted from the waste gases issuing from the chimney.

My invention also consists .of a novel disk so placed above the inlet-holes, which admit air into the Bunsen burner,that by raising or lowering the said disk a'srnaller or larger portion of the current of heated air passing through the burner-case is deflected into the Bunsen-burner inlet-holes, and thereby retarding'or accelerating its passage into the mantle and also directing the surplus hot air into the chimney at right angles.

Figure 1 represents a general elevation of an improved apparatus for incandescentmantle lighting. Fig. 2 represents a plan of the helix box. Fig. 3 represents a sectional elevation of thehelix-box. Fig. 4 represents a plan of the helix-coil. Fig. 5 represents a sectional elevation of the helix-coil. Fig. 6 represents a sectional elevation of the heatercone. Fig. 7 represents a sectional elevation of the air regulating and deflecting disk with an attachment which may'embody the principle of the oena contractor or the diverging cone for conducting the hot air to the inletholes in the base of the chimney.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates that portion of my new or-improved apparatus for incandescent-mantle lighting known as the heater,comprising A the helixbox, having a concave bottom A A the cover of the helix-box, which prevents leakage; A, the helix, whereby the incoming air is circulated; A the ornamental cap; A, the fastener for the cover, and A a non-conducting lining.

B designates the cold-air-supply pipe,which is' connected with A at the point B and having the cold-air inlet at 13 C designates the hot-air-supply pipe,which is attached to the cover of the helix-box A at the point C.

O designates the point of entry of the illuminant-supply pipe E into the hot-air'pipe C.

C designates detachable burner cases which inclose the space between the hot-air pipe 0 and the chimney, whereby anyintlow of unheated air is prevented.

C designates a screw for the purpose of securing O to the end of C.

C designates an aperture through which the burner-tap protrudes, enabling the same to be adjusted.

C designates slots cut in the top of C for the purpose of securing the gallery Z.

D designates the gas-supply tap, which cuts off the illuminant from the main supply.

E designates the illuminant-supply pipe, which is connected with the Bunsen-burner apparatus and which enters G at the point 0 E designates that portion of the illuminantsupply pipe E, which is surrounded with the hot air contained in the pipe 0.

F designates the point of connection of the pipe E with the Bunsen burner.

GdesignatestheBunsen-burner-regulating tap.

H designates the Bunsen burner or its equivalent.

H designates the air-inlets into the Bunsen burner.

I designates the incandescent mantle.

J designates the chimney, in which the perforations marked J and J are shown.

L designates the disk for regulating and deflecting the heated air into the Bunsenburner air-supply inlets.

L designates that portion of the attachment to the disk which may be made in the form of a head contracta or a diverging cone, whereby the hot air is directed into J through the perforations J 2 at right angles, as shown in Fig. 7.

L designates a binding-screw for the same.

K designates a helical coil, as shown in Figs. 4 and 5, whereby the air to be com sumed is circulated and heated.

K designates the helical-coil cover to prevent loss of heat.

K designates air-pipe unions.

K designates a non-conducting lining.

N designates a heater-cone, as shown in Fig. 6, comprising N, an inner cone or cones,

whereby the incoming air is circulated.

N designates an internal waste-air uptakepipe.

N designates the external hot-air pipe.

N designates the cover.

N designates the air-tight attachment.

N designates distance-pieces between the cones.

Z designates the gallery for supporting the chimney.

It will be apparent from the foregoing that cold air entering at B passing through I3, and entering A or its equivalent K or N at the point B must circulate through A or its equivalent K or N and will issue into C at the point C. As A is absorbing heat from the gases issuing from the chimney J it will be readily seen that the air passing as above described must become intensely heated. The hot air now in O on arriving at the point C envelops the illuminant-pipe E and during its course to H heats the illuminant contained therein. Heated air and the illuminant then enter the mantle through the burner in the usual manner, and a portion of the heated air passes up to and envelops the exterior of the mantle.

It is to he understood that while I have shown the illuminant-supply pipe E as entering the hot-air-supply pipe C at the point C I do not desire to be limited to that particular point, and I may have the entrance at any point nearer or farther away from the burner II, or I may have the illuminant-supply pipe entering the cold-air-supply pipe B and inclosed in A or its equivalent K or N. It is also to be understood that'while I have shown the perforations in the chimney as being circular and placed in rows I desire to reserve the right to have them of any shape or size and in any number or position above the base. It is also to be understood that while I have shown several forms of heaters I do not desire to be limited thereto, but may have them of any design most suitable for the purpose required. It is also to be understood that while I have shown the disk as being of a concave shape I do not desire to be limited thereto, but may have it either cone-shaped or flat or of any other shape, as may be most suitable for the purpose required.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1.
